Answer:
3x + 5y ≥ 800
Explanation:
Here, x represents the number of student tickets and y represents the number of adult tickets,
Also, the cost of each student ticket is $ 3 and the cost of each adult ticket is $ 5,
Thus, the total cost of the tickets = (3x+5y) dollars,
According to the question,
Total cost ≥ $ 800,
3x + 5y ≥ 800,
Which is the required linear inequality that can be used to find the combinations of adult and student tickets that they can sell to meet their goal.
